CAN-CAPPIN'G MIAGe-ima.

SPECIFICATION forming part of Letters Patent No. 588,337, dated August 17, 189'?.

` Application filed July Z, 1897.. .Serial No. 643,301. (No model.) i

tion.

.granted me January 1, 1895.

My said invention consists in certain improvements upon that for which Letters Patent of the United States No. 531,634 were Said improvements will be first fully described, and then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof and in which similar letters of reference indicate similar parts, Figure 1 is a view, partly in side elevation and partly in longitudinal vertical section, of amachine embodying my said invention,a portion of the height being broken away in order that the remainder may be shown on a larger scale; Fig. 2, a transverse sectional view as seen'when looking in the direction indicated by the arrows from the dotted line 2 2 in Fig. 1-Fig. 3, a fragmentary top or plan view, on an enlarged scale, of one of the canholding cups and the immediately-adjacent portion of the traylcarrying the cups; Fig. 4, a sectional view through the same as seen from the dotted line 4 4 in Fig. 3, and Fig. 5 a top or plan View of the upper end of one of the can-rotating spindles and driving device thereon.

The standard A, table B, driving-shaft C,

driving mechanism for the spindles D, the

frame E for such spindles, the rods F on which said frame is mounted, the treadle G, and bars H are respectively or may be similar to those shown and described in my Letters Patent No. 531,634,4 above mentioned, or of any other suitable form. The trays I, however, are

Extending down from the under side of the cup proper, within which the cans to be operated upon rest, is a flange, which passes through the orifice provided therefor in the frame or tray I, and passingthrough this flange, below the tray I, is a @otter-pin or suitable fasteningj, by which the cup J is prevented from being thrown out of place. Said can-receiving cups J, preferably, are entirely open in the center, and they are each provided at the bottom with a lug j, with which a similar lug or projection on the corresponding spindle-head may engage. These lugs preferably extend in horizontally from the rims or flangesV forming the lower portionsof the cups toward the centers of the central openings therein, as best shown in Fig. 3.

The spindles D are each provided with a head or cap D', having an upwardlyeextending pin or projection d', which is adapted when the spindle is raised to be thrown into the path of the lug j, and thus the can-carrying cup J is positively driven by the spindle D whenever the latter is raised, while when the spindle is lowered to its normalposition. the parts are entirely free of engagement. The cans are never disturbed from the positions they occupy when first pnt in place until removed from the machine, whereas in my former machine they were raised oftY the tray upon which they were placed by the head on the spindle, which came in direct contact therewith. The pressure in my new machine is always against the outer edge of the cans directly under their sides, while in the former arrangement, with large-sized cans especially, the pressure was in the center, thus having some tendency to push the ends of the cans in. The present arrangement is obviously the better one, as will be readily apparent to those skilled in the art.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a can-capping machine, of a suitable tray or frame, can-receiving cups mounted in said tray or frame and having lugs at the lower side, driving-spindles positioned below said cups and provided with heads having upwarelly-extending projections adapted to engage with the lugs on the cups, whereby, when the spindles are raised, said cups are positively engaged and driven, substantially as set forth.

2. The combina-tion, in a can-capping ma- `chine, with the standard, the table, the driving-shaft, the can-rotating spindles and the can-holding bars; of trays I having orifices :o therein, can-receiving cups mounted in said orifices, and heads on said spindles adapted when said spindles are raised to come in contact with, raise and revolve said ou ps, substantially as shown and described.

3. The combination, in a can-capping machine, of the framework, the driving m echanism, the tray I having orifices, can-carrying cups mounted in said orifices and extending through to below the same, pins j whereby 2o said cups are prevented from being entirely removed from said orices, and spindles D having heads D which are adapted to come in contact with and raise and revolve said cups without removing them irom the orifices in the tray, substantially as shown and described.

4. The combination, in a can-capping Inachine, of a tray or frame I having oriices to receive the vertical portions of the can-carrying cups, said cups having several annular seats of different diameters to receive different-sized cans, with a free opening through the center to the bottom, a lug within said opening, a driving-spindle, a head on said spindle adapted to come in Contact with thel under side of the cup and provided with a projection adapted to engage with the lug in the opening therein,a1l substantially as shown and described.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 25th day of June, A. D. 1897.
